8 阅读理解。 My son Karl talked little after his father died. As a single parent, I tried to do my best to talk to him. But the more I tried, the more withdrawn he became. His report card arrived, saying that he had been absent 95 times from classes and failed in the exams. I sent him to the school advisor, and I even begged him. Nothing worked. One day, I was at work when I got a phone call. A man introduced himself as the headmaster. "I want to talk to you about Karl"s absences." Before he could say another word, all my disappointment and sadness over Karl came pouring out into the ears of this stranger. "I love my son but I just don"t know what to do. I"ve tried everything to get Karl to go back to school and nothing has worked. It"s out of my hands." For a moment there was silence on the other end of the line. The headmaster seriously said, "Thank you for your time", and hung up. Karl"s next report card showed marked (显著的) improvement in his grades. Last week I attended a parent- teacher meeting with Karl. His teachers praised him a lot and were amazed at the way he had turned himself around. On our way home, he said, "Mum, remember that call from the headmaster last year?" I nodded. "That was me. I thought I"d play a joke but when I heard what you said, it really hit me how much I was hurting you. That"s when I knew I had to make you proud." 1.
